The loss of a longtime partner can often serve as a wake up call, and for PepsiCo, the departure of KFC feels particularly poignant. After four decades of association, including a period when Pepsi actually owned the fried chicken giant, KFC announced it will replace Pepsi products with Coca-Cola across its 3,700 U.S. locations this January. While the move represents only a small fraction of total sales, it serves as a visible symbol of the eroding brand power that has plagued the cola titan in recent years.

The gap between the two rivals has widened significantly since the era of flashy celebrity endorsements and high stakes taste tests. Once separated by only a few percentage points in market share, Pepsi now trails far behind Coke’s dominant lead. The slide reached a historic low in 2024 when Pepsi dropped to third place in the U.S. carbonated soft drink market, falling behind Dr Pepper for the first time ever. This decline highlights a strategic divergence where Coca-Cola focused intensely on brand innovation and lean operations while Pepsi evolved into a diversified conglomerate.

For years, PepsiCo executives essentially left their soda business on autopilot, distracted by the massive success of their Frito Lay snack division. Because chips and dips offered far higher profit margins than sugary drinks, investments flowed toward Doritos and Cheetos rather than promoting the flagship cola. This strategy worked as long as snack sales soared, but inflation has recently caused consumers to push back against rising chip prices, leaving the company vulnerable just as they realized their beverage wing had stagnated.

CEO Ramon Laguarta has openly admitted that the beverage side of the house requires urgent attention and renewed focus. To stem the tide, the company is looking to ramp up marketing spending and expand its portfolio through acquisitions like prebiotic soda maker Poppi. However, some activists believe these tweaks aren’t enough and are calling for a complete corporate divorce between the food and drink divisions to unlock hidden value and force a dedicated return to winning the cola wars.
